To answer Matt's question, yes, it is up to the nVidia driver to control the brightness control.
I've a T530 running Fedora and the backlit display works after resume. I'm using the nVidia proprietary driver and added the following line under the "Device" section in the Xorg conf file (/etc/X11/xorg.conf) Option "RegistryDwords" "EnableBrightnessControl=1" Hope that helps! -Andrew -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1083984 Title: Brightness control doesn't work on Lenovo Thinkpad T530 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1083984/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
